TEMPERATURE GUARD - 3 x PT100 ELEMENT KPM303x • 3-channel Temperatur Guard for 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 • One fast analogue output (<50mS), F-versions Specifications Auxiliary Voltage: 100-120, 200-240, 380-415V, 440-460 or 480VAC 40-70Hz (Fuse 0,5A) Optional Auxiliary Voltage: DC Input signal: Scale Range: Contact rating: Adjustments Trip Warning: Trip Alarm: Analogue outputs: F-Versions Temperature: Weight: Front protection: 24, 48 or 110VDC (Fuse 2A) 0-10, 0-20 or 4-20mA Variation of ranges between -150 to +850 Degrees °C Can also be scaled in Fahrenheit: -238 to +1562°F AC: 100VA -250V/2A max. DC: 50W -100V/1A max. Trip level Delay 0-100% of FSD 0-30 secs 0-100% of FSD 0-30 secs Up to 20mA, max 500ohm Up to 10V, min 100kohm -20 to +70ºC 0.6kgs IP54 (IP65 optional) The KPM303x is a digitally controlled temperature guard/controller for monitoring of temperature of machine bearings, windings etc. The warning relay can be used to trip nonessential load or start a cooling fan and the alarm relay may be used to trip the total load. KPM303x can be scaled for a wide variation of ranges between -150 and up to 850 Degrees Celsius or to a 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: -ALARM - WARNING - NORMAL KPM303C 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 Gversions). The unit meets IEC60092-504 and the relevant environmental and EMC tests specified in IEC60068/60092 and IEC61000/60533 respectively, to comply with the requirements of the major Classification Societies.

TEMPERATURE GUARD - 3 x PT100 ELEMENT Relays shown de-energised, a fail-safe relay energises when the unit is powered. Relay Reset Any latched relay is reset by linking terminals 30 and 31 or by interrupting the voltage input to terminal 1. Relay Operation Customer setting PT 100 type must be sett by custmer Relay Configuration: Cascade Fail Safe Analogue Output All F-versions have an analogue output proportional to meter reading. The signal is specifically intended as input to a control system or for remote monitoring of the measured parameter. Other outputs available on request. Add...
