KPM30x - TEMPERATURE GUARD - SINGLE PT100 ELEMENT
- Temperatur Guard for a single PT-100 element (RTD)
- 2, 3 or 4-wire PT 100 connection via external converter
- Triple relay for more flexibility
- A wide range of scaling available
- Very fast analogue output (<50mS), (F-version)
Features
The KPM30x is a digitally controlled temperature guard/controller for monitoring of temperature of machine bearings, windings etc.
The warning relay can be used to trip non-essential load or start a cooling fan and the alarm relay may be used to trip the total load.
KPM30x can be scaled for a wide variation of ranges between -150 and up to +850 Degrees Celsius or to Fahrenheit scale.
An AC or DC auxiliary voltage is required for the unit. A green LED indicates POWER on. Start of monitoring function is delayed when power is switched on (default 2 secs delay). In this way false tripping during power up is avoided.
The precision DIN96 moving coil meter reads the monitored parameter, and has low-reflection glass to ease reading at a distance.
The triple-zone status LEDs at a glance gives the clear safety message:
KPM30C is the standard version with no analogue output. The optional F-versions has an isolated analogue output signal proportional to meter deflection.
The units three C/O relay outputs and trip levels and trip delays are user settable on unit rear to suit most applications.
Relay trip lamps (Red LED) flash instantly (approx. 1 flash per second) when the trip level is passed, the relay trips after elapsed delay. The lamp changes state and the trip relay operates after the pre-set delay. If a trip condition ends during the delay interval, the timer will automatically reset.
As standard the unit is supplied for automatic reset. Manual reset (latching relays) is optional (All G-versions).
The unit meets EN 61010-1 Cat. III, Pollution degree 2 and the relevant environmental and EMC tests specified in EN 61326-2-4 to comply with the requirements of the major Classification Societies.
