VOLTAGE OUTPUTS FOR SSR DRIVE
Fig. 9 SSR DRIVE OUTPUT WIRING
It is a time proportioning output.
Logic level 0: Vout < 0.5 V DC.
Logic level 1:
24 V + 20 % @ 20 mA.
Maximum current = 20 mA.
NOTE: This output is not isolated. A duble or reinforced
isolation between instrument output and power supply must
be assured by the external solid state relay.
LINEAR OUTPUT
This instrument is equipped with one isolated linear output
(OUT 1) programmable as:
- main output (heating or cooling)
- secondary output (cooling)
- analog retransmission of the measured value
- analog retransmission of the operative set point.
Fig. 10 mA OUTPUT WIRING
Output type: isolated 0 - 20 or 4 - 20 mA programmable.
Maximum load: 500
W .
Resolution:
- 0.1% when used as control output
- 0.05 % when used as analog retransmission.
