RMU5: Full Features List

Four galvanically isolated, bi-polar analog input channels configurable for +/-158mV, +/-7.5V, and +/-175V
Each channel can measure DC and AC RMS voltages (i.e. induced AC measurements)
>70dB line AC rejection when measuring DC signals provides stable DC measurements
All analog channels are high impedance to allow direct connection to reference half cells
All analog channels are 4-20mA transducer input capable
Multi-stage surge protection and galvanic isolation provide maximum lightning immunity
Programmable alarm window capability on all input channels
One digital input capable of dry contact or voltage input (optically isolated)
One switched digital interrupter relay output with 750mA sinking capability
Integral health monitoring of internal voltages and temperature
20x4 character wide-temperature range LCD screen for local status monitoring with no additional equipment
Two push button switches to allow scrolling of LCD information screens
Bright, dual color status LED indicators
NEMA 4X, IEC529 Type IP65 enclosure for harsh environments
Enclosure is equipped with pad-lockable quick release latches
