The FE-MM4 is a DC powered 4 channel version of its larger brother the FE-MM8. In common with all chassis styles in the Micro Analog 2 range, it accepts a range of dual channel signal conditioning modules which together cover almost every transducer type. The FE-MM4 has slots for up to 2 dual channel modules. The FE-MM4 may be specified with an auto zero function which controls the automatic offset removal for any FE-366-TA bridge transducer amplifiers. (If you need this function specify FE-MM4-AZ when ordering.) Inputs are via the dual channel 7 pin rear panel connectors which can accept a variety of connector adaptors and outputs are via the rear panel15 way D connector which accepts the FE-MAC8C BNC adpator unit.
The front panel is easilly removed to allow any of the Micro Analog 2 modules to be inserted into any position. Configuration and operation is simple, and the rear panel connector may be connected to BNC adaptors or connected using an adaptor to any data acquisition system.
