| 3RS1440-2HB50 | 0.28 | 41H | TEMPERATURE MONITORING RELAY FOR IO-LINK PT100/1000. KTY83/84. NTC 2 LIMIT VALUES -50 DEGR. C TO 750 DEGR. C 3X1W. WIDTH 45 MM SPRING-LOADED TERMINAL | 339.25 |
The 3RS14 and 3RS15 temperature monitoring relays for IO-Link are used to measure temperatures in solid, liquid and gas media. The temperature is calculated using a sensor in the medium, evaluated by the device and monitored for overshooting or undershooting a working range (range monitoring). The digital temperature monitoring relays have two separately adjustable limit values, are non-volatile and can be operated as desired using the open- or closed-circuit principle.
The devices differ in terms of the number of temperature sensors which can be evaluated. The 3RS14 40 and 3RS15 40 for IO-Link temperature monitoring relays can be digitally adjusted for one sensor and represent an alternative to temperature controllers in the low-end section (two-point or three-point control).
The devices with two-point control can, for example, be used as a thermostat. The devices with three-point control can, for example, independently switch between heating and cooling.
The 3RS14 41 temperature monitoring relays for IO-Link can be digitally configured to evaluate up to three resistance sensors at one time. The devices were designed specifically for monitoring motor windings and positions.
The temperature monitoring relays are powered through the control supply voltages IO-Link (L+) and earth (L-) or via an external 24 V DC power supply.
Monitoring
Once the temperature has reached the set threshold 1, the output relay K1 changes its switching state as soon as the set timet has elapsed (the K2 output relay responds in the same manner to 2). The delay time can be adjusted.
The output relays return immediately to their original state once the temperature reaches the respective hysteresis value.
When the temperature reaches the upper limit value 1, the output relay K1 changes its switching state as soon as the set timet has elapsed. The output relay returns immediately to its original state once the temperature reaches the respective hysteresis value.
K2 responds in the same manner to the lower threshold 2. Both thresholds, 1 and 2 can be parameterized for overshooting or undershooting. This makes it possible to use a limit value for issuing an alarm signal to announce that a value a limit value is about to be overshot or undershot.
Note:
The "Temperature monitoring mode" parameter can be used to set the desired type of monitoring (monitoring for overshooting or undershooting or range monitoring).
