TEMPERATURE -50ºC to +450ºC INDICATOR / MONITOR temperature probe NOT INCLUDED
These devices are designed to interface directly with 3 Wire Pt 100 Probe.
The relay(s) may be set to control from either probe, or the difference in temperature between the two.
The relays may be configured as either control or alarm functions in either heating or cooling applications.
When configured for alarm applications, the latch facility may be used to keep the relay in the fault condition until the latch is removed.
The maximum and minimum temperatures are recorded for a period of 24 hours. This is useful when troubleshooting or analizing the overall system’s performance.
The parameter settings may be locked and code protected to avoid changes from being made by unauthorized personnel.
The menu may be reduced to allow changes to only the most commonly adjusted parameters. This reduces the risk that one of the mode advanced parameters are accedentally changed.
The adjustable range of the temperature set points may be limited to avoid temperatures from being enetered that may cause damage to the overall system.
These devices do NOT incorporate any relays and are used to display the temperature read from the probe.
ADDITIONAL FEATURES INCLUDE:
SET POINT for relay 1 and relay 2
HYSTERESIS for relay 1 and relay 2
RELAY FUNCTION: HEAT/COOL CLIMATE CONTROL (2 Relay device only)
Temperature controller with isolated re-transmit:(4-20mA or 0-10V) others on request
• configure the device to re-transmit the temperature read as a 4-20mA loop, or 0-10V voltage output
• device may be used as a programmable temperature transducer.
• re-transmit the full scale of the the device, or any part thereof.
• eg. with the re-transmit offset set to 50, and the span to 100, 50 °C temperatures will produce 4mA and 150 °C (50+100) will produce 20mA
