S7M - Description
The S7M is an AC powered oscillator/demodulator signal conditioning unit for use with a wide range of inductive (e.g. LVDT or half-bridge) transducers. A high stability oscillator provides sinusoidal excitation and a synchronous demodulator provides high level voltage or current outputs.
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 65 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.
