RM4150 and RM4151 Unit Overview
The RM4150 and RM4151 are housed in a NEMA-rated weatherproof enclosure. They are designed primarily for cathodic protection applications and supports two-way communication with the Bullhorn Web website using the GSM cellular network. The units support an optional relay connection for GPS-synchronized current interruption.
The RM4150 supports two (2) configurable digital and five (5) configurable analog inputs with the following specifications:
-
Input ANALOG CH 1 through ANALOG CH 5 (channels 1 through 5) are isolated inputs that support analog ±150 V DC, 150 V AC, 4 - 20 mA with external resistor, or active digital input devices.
-
Input DIGITAL CH 1 and DIGITAL CH 2 are non-isolated inputs (0 - 24 V DC) that support digital dry contact closure and active digital input devices. DIGITAL CH 1 can also be used as a pulse count accumulator, and DIGITAL CH 2 can be used as an accumulator reset.
