Physical Dimensions and Mounting

This module measures 130 mm in width and 110 mm in height. Its depth reaches 55 mm for shallow cabinet fits. The unit weighs 380 grams, so installation requires minimal mechanical support. Four clip-locks secure the module onto a standard DIN rail. For removal, simply press the top latch and pull outward.

Internal Architecture and Energy Storage

Ninety-two discrete components populate the internal printed circuit board. Three electrolytic capacitors form a 2200 µF energy storage bank. This bank provides transient protection for short power interruptions. Consequently, the module prevents unexpected resets during momentary voltage dips. This design maintains stable signal acquisition across all 32 channels. Each channel also includes individual optocouplers for signal isolation.

I/O Interface and Connectivity

The expansion module provides 32 mixed discrete I/O points for field devices. You can configure sixteen points as digital inputs for sensor readings. The remaining sixteen points function as transistor outputs for actuator control. A 16-pin backplane connector handles high-speed communication with the CPU. This connector includes a locking latch to prevent accidental disconnection. You can also mix inputs and outputs flexibly according to your application needs. Accordingly, this unit offers expansion without requiring additional chassis slots.

Power Requirements and Protection

The module accepts a 24V DC power supply with ±15% tolerance. It draws only 85 mA of current under normal operation. Internal protection circuits guard against reverse polarity and overvoltage. Therefore, the module survives harsh industrial power conditions reliably.
