ADM51C-2 Yokogawa Contact Output Module

Hardware Specifications

Contact Output Signal Characteristics

The ADM51C-2 switches transistor contact outputs for discrete control signals. Each output point supports resistive or inductive loads up to 30 V DC and 100 mA.

The module provides several output modes. Status output maintains the commanded discrete state, while pulse output produces a defined switching interval. One-shot pulse width output uses the configured pulse duration, and time-proportional ON/OFF output controls the switching ratio over time.

The module provides point-by-point signal isolation. This configuration separates individual output channels electrically and limits direct signal interaction between points.

Frequently Asked Questions

Q: What load can the ADM51C-2 transistor contact output handle?
A: The specified contact rating is 30 V DC and 100 mA or less for resistive or inductive loads.

Q: What pulse width can the ADM51C-2 generate?
A: The pulse width setting ranges from 0.1 to 7200 s, with a 20 ms resolution.

Q: Which terminal boards are compatible with the ADM51C-2?
A: The supplied specifications identify TE16 and TE32 terminal boards as compatible terminal boards. The module uses KS2 or KS3 cabling.

Field Installation Guidelines

Install the ADM51C-2 in the designated I/O module nest and connect the field wiring through the specified KS2 or KS3 cable arrangement.

Verify the selected TE16 or TE32 terminal board before wiring the output channels. Check the external load voltage and current against the specified 30 V DC and 100 mA maximum contact rating.

Route output wiring separately from high-voltage power conductors where practical. Maintain appropriate physical separation to reduce unwanted electrical coupling.

Terminate cable shields according to the control-system installation standard. Avoid creating unintended shield-current paths through multiple grounding points.

Before energizing the circuit, verify channel assignments, output polarity, external load wiring, and terminal connections. Confirm the configured output mode and pulse parameters against the control application.
