FAQ

Q1: What is the Yokogawa AMM25C used for?
It is a 15-channel mV input multiplexer module with a dedicated thermocouple interface and RJC input port for CENTUM CS/VP DCS systems, used to acquire low-level analog signals (DC voltage, mV, thermocouple, RTD) from field sensors .

Q2: How many channels does it have?
15 input channels. Channel 16 is dedicated to the RJC (Reference Junction Compensation) port .

Q3: What is the difference between AMM22C and AMM25C?
The AMM22C is a 16-channel mV input multiplexer without a dedicated RJC input port. The AMM25C provides 15 input channels plus a dedicated RJC input port for thermocouple reference junction compensation .

Q4: What is the input range?
For mV: -100 to +100 mV DC. For DC voltage: -10 to +10 V DC. For RTD: -200 to +600 °C .

Q5: What cable is required?
The AMM25C requires a KS1 cable for field wiring (connector type) .

Q6: Does it provide channel-to-channel isolation?
Yes, input signals are isolated between systems with a withstanding voltage of 1500 V AC/min .

Q7: What is the burnout detection behavior?
Selectable UP / DOWN / OFF. When a thermocouple breaks, the signal can be forced to a known state to trigger alarms .

Q8: Is this a current or legacy product?
The AMM25C is associated with CENTUM CS/VP systems and is primarily sourced as a spare part for existing installations. Confirm current availability with Yokogawa or an authorized distributor.

Q9: Where can I get technical documentation?
The official Yokogawa product print page (tek-international.com) is the most authoritative source in the search results for the AMM25C specification . For the exact order number, consult Yokogawa or an authorized distributor.
