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.

2 RELAYS

Each relay may be used as either a control or alarm relay for either heating or cooling applications.
The relays are configured independantly. (one may be set for control while the other is used as an alarm relay).
When using multiple probes, each relay may be allocated to work with either probe.

ADDITIONAL FEATURES INCLUDE:

  • keypad lock with code


ADJUSTABLE PARAMETERS:

SET POINT for relay 1 and relay 2

HYSTERESIS for relay 1 and relay 2
