'Micro Sensor MPM/MDM4881 Pressure / Differential Pressure Transmitting Controller Features • Real-time pressure display in unit: Bar or MPa • 14-segment LED display • Button programming, easy operation • Max. 5 relays control independently, time-delay function • Switchable analog output • Record the Max. pressure during operation(button for clearing up) • Support back, rail, cover and joint mounting • Hardware wrong operation protection • Intrinsically safe products conform to GB3836.1 and GB3836.4 standards, and have explosion-proof certification, Exia mark is Ex ib IIA T6 Gb. • Modbus communication MPM/MDM4881 Pressure/ Differential Pressure Transmitting Controller is a digital meter integrating pressure measurement, display, transmitting and control. It adopts the internationally advanced ARM processing chip. By compensation and adjustment of the sensor, MPM/MDM4881 can achieve precise measurement, quick response & control of multiple relays. The controller supports peak value record and action delay, providing 4 digit LED display, easy for reading. 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 and joint mounting. Whole product protection is IP65. MPM/MDM4881 supports 5-relay + 1-analog output. It can be applied for long distance pressure measurement and control in the equipment automatic pressure detection, action control and water level alarm etc. It is also a preferred choice for working fields where request high frequency / high accuracy switchover or mechanical pressure relays is incompetent. Specification Input Power Supply: Non Intrinsically Safe: (220±44)V AC/22V~32V DC; Intrinsically Safe: 22V~28V DC (Supplied by Safety Barrier) MICRO SENSOR CO.,LTD
