AMM12C Voltage Input Multiplexer Module Yokogawa

Hardware Specifications

Yokogawa Process Signal Interface

The AMM12C handles analog voltage signals between field-side wiring and the control-system signal path. Its stated input and output ranges extend from -10 V to +10 V DC, while the module provides 16 channels per module.

Channel isolation and insulation resistance support electrical separation between signal paths. Therefore, installation should maintain appropriate separation between analog wiring and power or high-noise circuits.

Frequently Asked Questions

Q: What voltage range does the AMM12C support?
A: The supplied specifications state an input and output range of -10 V to +10 V DC.

Q: How many channels does one AMM12C provide?
A: The supplied data specifies 16 I/O channels per module.

Q: What is the specified switching time?
A: The maximum stated switching time is 10 ms.

Field Installation Guidelines

Install the AMM12C in the designated Yokogawa rack or mounting environment and secure the module according to the applicable system hardware procedure. Connect field voltage signals to the specified terminal blocks and verify polarity before energization.

Route analog signal wiring separately from AC power, switching circuits, and other high-noise conductors. Where shielded cable is used, terminate the shield according to the Yokogawa system grounding specification and avoid creating unintended ground loops.

Before commissioning, verify that each connected signal remains within the specified -10 V to +10 V DC range. Also confirm terminal assignments, insulation condition, channel wiring, and rack compatibility before applying operating power.
