Physical Dimensions and Mounting

This module measures 125 mm in height, 45 mm in width, and 160 mm in depth. The unit weighs approximately 0.40 kg. It mounts directly onto a standard DIN rail within the Series C cabinet. The front panel includes 8 LED indicators for output status monitoring. These LEDs show active channels and fault conditions clearly.

Electrical Interface and Field Wiring

A 50-pin D-sub connector serves as the primary interface for all field wiring. Each channel provides a two-wire termination for 4–20 mA current loop devices. The module includes an internal 24 VDC loop power supply for each channel. This built-in power eliminates the need for external power sources. Field devices like I/P transducers, valve positioners, and chart recorders connect directly to these terminals. The module operates in sourcing mode only for standard compatibility.

Performance and Signal Integrity

The MC-PAOY22 80363969-150 delivers 14-bit resolution with exceptional linearity across the full output range. It updates all 8 channels simultaneously for coordinated control response. The module includes built-in diagnostics for open-loop and short-circuit detection. It reports any output anomalies to the main controller immediately. Furthermore, the output circuitry provides ESD protection for reliable operation. The maximum loop resistance capability reaches 750 Ω at 24 VDC.

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 loop wiring polarity matches the termination diagram. For critical control loops, consider using redundant modules for fail-safe operation. Ensure that the total loop resistance does not exceed the specified maximum. Test each output channel before connecting critical field devices.

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 ingress. This coating enhances long-term reliability in demanding plant environments.
