Description
Matsushima Position Encoder Transmitter has a high precision gear mechanism and a position transmitter built-in and used for degree of opening indication of valves, gates, dampers, etc. as well as for control of the rotation, travel, swiveling, elevating and lowering positions.
It can also accommodate a requirement for a backlashless gear mechanism and a zero-point adjustment mechanism that allows for fine adjustment of reference position with the shaft being connected. Positioning control Ambient temperature -10?C to +50?C Protection category IP55.
Matsushima Position Encoder Transmitter Alarm Output
Every time a new input is sampled, the JRQ2 compares the measured signal to a preset threshold and provides a relay the output which trips either when the input is above the set point or below the setpoint as predetermined.
The threshold and its deadband are programmable as a percentage of the input range: -15 to +115% for the threshold and 0 to 20% for the headband. Once the relay is tripped, it is not reset until the signal goes to the opposite direction by the preset deadband from the threshold level.
For example with High alarm, the relay turns on when it exceeds the setpoint, and turns off when it goes below the setpoint by the deadband.
Reset Input
When a reset input is turned on, the accumulated count in the internal counter goes back to zero. The JRQ2 compares the input to this internal count, therefore is affected by re-set operations. The reset input negative is connected to the input common.
