Technical Data

General

The measuring modules of the MM-232.xx series are intelligent modules for a range of measuring applications. The modules are designed to be connected to the serial interface (9600 baud, no parity, 8 data bits, 1 stop bit) of all standard computers, microprocessor systems and terminals. They can also be connected to a modem, enabling remote data transmission and monitoring without a computer at the measuring point.

Versions

• MM-232.20 – 4 analog inputs, 2 digital inputs, 2 digital outputs
• MM-232.21 – 4 frequency inputs, 2 digital inputs, 2 digital outputs
• MM-232.22 – 6 digital inputs, 2 digital outputs
• MM-232.23 – 4 counter inputs, 2 digital inputs, 2 digital outputs
