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.
| Model | Description | When to Choose |
|---|---|---|
| AMM25C | 15-channel mV input multiplexer with RJC port, connector type | When thermocouple measurement with dedicated RJC and pre-fabricated cabling is required in CENTUM CS/VP |
| AMM22C | 16-channel mV input multiplexer, connector type (no dedicated RJC port) | When 16 channels are needed without the dedicated RJC port (confirm differences with Yokogawa) |
| AMM22T | 16-channel mV input multiplexer, terminal type | When direct screw-terminal wiring is preferred (confirm with Yokogawa) |
| AMN32 | I/O carrier/nest for AMM-series modules | When the mounting baseplate is required for AMM25C installation |
| KS1 Cable | Mating cable for AMM25C | When field wiring is required for the connector-type module |
