Physical Dimensions and Mounting

This module measures 125 mm in height, 45 mm in width, and 160 mm in depth. The unit weighs approximately 0.42 kg. It mounts directly onto a standard DIN rail inside the cabinet. The front panel includes 16 LED indicators for per-channel output status. These LEDs show active and fault conditions clearly.

Electrical Interface and Field Wiring

A 50-pin D-sub connector serves as the primary interface for field wiring connections. Each output channel provides a sourcing (PNP) configuration for 24 VDC loads. The module includes built-in short-circuit and overcurrent protection on every channel. This protection prevents damage to the output stage during fault conditions. External devices like solenoid valves, motor starters, and indicator lamps connect directly to these terminals.

Performance and Output Characteristics

The 42622268-002 delivers 0.5 A per channel with a total capacity of 8 A continuous. It switches outputs with minimal delay for responsive control actions. The module includes internal flyback diodes for inductive load protection. These diodes suppress voltage spikes during load de-energization. Furthermore, the module performs output state verification through feedback monitoring. This feedback ensures that commanded states match actual output conditions.

Installation and System Integration

You can install this module in any available I/O slot within the Series C chassis. The backplane automatically handles address assignment and power distribution. Always verify the load current does not exceed per-channel ratings. For high-current applications, use external interposing relays for load switching. Connect the field wiring according to the termination diagram provided. Test each output channel individually before connecting critical actuators.

Environmental Compliance and Certification

This module carries CE marking and UL recognition for industrial applications. It also complies with RoHS and WEEE environmental directives. The conformal coating protects the PCB against moisture and dust. This coating enhances long-term reliability in demanding plant environments.
