MTM4881 Temperature Transmitting Controller - 1

1MicroSensor MTM4881 Temperature Transmitting Controller (V1.4) Features • Real-time temperature display in unit: °C or °F • 14-segment LED display • Button programming, easy operatio • Record the Max. in operation(button for clearing up) • Support rail, cover and back mounting • Hardware wrong operation protection n • Max. 4 relays control independently, time-delay function • Switchable analog output • Intrinsically safe products meet GB3836.1 and GB3836.4 standards, and have explosion-proof certification, Exia mark is Ex ib IIA T6 Gb • MODBUS communication Introduction MTM4881 Temperature Transmitting Controller is an intelligent meter integrating temperature measurement, display, transmitting and control. It adopts the internationally advanced ARM processing chip. By compensation and adjustment of the sensor, the product can achieve precise measurement and provide quick response and control of multiple relay. The meter supports peak record and action delay, providing 4 digit LED indicator, easy for reading. And the design of multiple buttons makes the operation easier and more convenient. Either current or voltage output signal is optional. It supports back mounting, rail mounting, cover mounting. Whole product protection is IP65. MTM4881 Temperature Transmitting Controller provides 4-relay output + 1 analog output, which is applied in liquid medium’s temperature measurement, especially suitable for detection of oil temperature of hydraulic and lubrication transmission system. Specification Input Power Supply: Non Intrinsically Safe type: (220±44)V AC / 22V~32V DC; Intrinsically Safe type: 22V~28V DC(power supplied by Safety Barrier) Temperature Range: -30 C ~150 C / -22 °F ~302°F.
