Product Overview
The TOSHIBA HC422B is a robust industrial logic module engineered by Toshiba—a trusted leader in industrial automation components—designed to execute precise logic control tasks in diverse industrial environments, including manufacturing lines, packaging machinery, and process control systems. As a key building block for automated workflows, this module excels in translating input signals from sensors, switches, and other devices into actionable output commands for actuators, valves, or motors—ensuring seamless coordination of equipment. Core features of the TOSHIBA HC422B include 8 digital input channels (24V DC) and 4 digital output channels (24V DC, 2A per channel), support for standard logic functions (AND, OR, NOT, flip-flops), and a compact DIN-rail mount design that optimizes cabinet space. With its high noise immunity (compliant with EN 61000-6-2) and wide operating temperature range, the TOSHIBA HC422B maintains reliable performance in electrically noisy settings (e.g., near high-power motors) and harsh conditions (e.g., food processing plants with temperature fluctuations). Additionally, the TOSHIBA HC422B features pluggable terminal blocks for quick wiring and replacement, reducing downtime during installation or maintenance—making it ideal for both new automation setups and retrofits of legacy systems.

Key Features and Benefits
Flexible Logic Control & Easy Configuration
The TOSHIBA HC422B simplifies logic control with pre-programmed essential functions, eliminating the need for complex coding or specialized software. Users can configure logic operations (e.g., “activate output 1 if input 1 AND input 2 are high”) via front-panel DIP switches—no programming experience required. This accessibility makes it ideal for technicians tasked with quickly setting up basic control loops, such as a packaging machine’s “start” sequence (triggered by a product sensor and a safety guard switch). The module also includes a built-in timer function (adjustable from 0.1s to 100s), enabling time-delayed actions like “keep a conveyor running for 5 seconds after the last product is detected”—a common requirement in assembly line workflows. With 8 inputs and 4 outputs, the TOSHIBA HC422B offers enough I/O to handle small-to-medium control tasks, while its PNP/NPN configurable inputs ensure compatibility with most industrial sensors (e.g., inductive proximity sensors, photoeyes).
Industrial-Grade Reliability & Noise Immunity
Built to withstand the demands of factory floors, the TOSHIBA HC422B features a rugged plastic housing with flame-retardant properties (UL 94 V-0) and conformal coating on internal circuits—protecting against dust, moisture, and chemical exposure (e.g., cleaning agents in beverage plants). Its wide operating temperature range (-10°C to +60°C) ensures performance in unconditioned cabinets, such as those in outdoor pumping stations or cold-storage facilities. Critical to industrial environments, the module’s high noise immunity filters out electrical interference from nearby equipment (e.g., variable-frequency drives, welding machines) that could cause false input signals or unexpected output triggers. For example, in an automotive stamping plant, the TOSHIBA HC422B reliably processes signals from a metal detector sensor despite electromagnetic noise from stamping presses—preventing costly production errors like uninspected parts moving to the next station.
Quick Installation & Low Maintenance
The TOSHIBA HC422B is designed for efficiency throughout its lifecycle. Its pluggable terminal blocks allow technicians to pre-wire cables offline, then quickly connect the module to the DIN-rail—cutting installation time by up to 40% compared to hard-wired modules. If a module needs replacement (e.g., due to accidental damage), the pluggable terminals enable swap-outs in minutes without rewiring the entire circuit—minimizing downtime for 24/7 operations. The module’s short-circuit protection adds another layer of low-maintenance reliability: if an output channel is shorted (e.g., a damaged wire to a solenoid valve), the module automatically shuts down the affected channel and recovers once the fault is fixed—no manual reset or component replacement required. Front-panel LEDs for power, input status, and output status also simplify troubleshooting, allowing technicians to quickly identify issues like a failed sensor (no input LED) or an overloaded output (flashing output LED).

Typical Application Areas
- Manufacturing Automation: Controlling small assembly line stations (e.g., activating a robotic gripper when a part is detected by a photoeye, using the TOSHIBA HC422B’s AND logic to ensure safety guards are closed first).
- Packaging Machinery: Managing “fill-and-seal” cycles (e.g., triggering a filler valve when a container is in position, then a sealer 2 seconds later via the module’s timer function).
- Material Handling: Operating conveyor systems (e.g., stopping a conveyor if an overload sensor or emergency stop button is activated, using the module’s OR logic for fault detection).
- Food & Beverage Processing: Controlling simple mixing processes (e.g., turning on a mixer only if a hopper level sensor indicates material is present and a safety lid is closed).
- Building Automation: Managing HVAC auxiliary equipment (e.g., activating a supply fan if a room temperature sensor exceeds 25°C and the main HVAC unit is running).
