3.3.2 Analog input / relay / hybrid connections
Note.
Tighten terminal screws to a torque of 0.1 Nm (0.9 lbf.in).
Analog inputs:
– 3-Lead RTD:
3-leads must have equal resistance, not exceeding 20
each
– mA input types:
to ensure loop continuity when the recorder is switched off, fit a suitably rated diode (for
example, type 1N4148 or equivalent)
– using an external cold junction:
any channel can be used as the external cold junction for any thermocouple. When a
thermocouple channel is using an external cold junction RTD, the thermocouple channel must
have the shorting link RVG200/0118 fitted instead of the thermistor assembly
