S7MZ - Description
The S7MZ is a high gain version of the S7M and is an AC powered oscillator/demodulator signal conditioning unit for use with load cells or similar quarter-, half- or full-bridge resistive transducers and inductive devices with a very low output.
A high stability oscillator provides sinusoidal excitation and a synchronous demodulator provides high level voltage or current outputs.
Further options include T (dual limits) or E (max/min store) which may also be used with Option Z, but T and E cannot be used together.
The module may be orientated in any direction but preferably with the glands facing away from any splashing, etc. Resistance to humidity is consistent with the IP rating.
The supply voltage is normally set to 230v unless specified otherwise by the user. If this is changed from that indicated on the label then the label must be changed accordingly.
The unit should be protected from the effects of excessive shock and/or vibration.
