Dräger Regard 3900 4 - 20mA Input Module Each analog input board caters for one to four, 2 or 3 wire, 4-20mA transmitters. Each transmitter connects to dedicated field terminals. Up to a total of four analogue input boards can be installed in to a single Dräger REGARD 3900, thus giving a maximum input count of sixteen transmitters. Each individual input board is populated with three relays. These relays offer common Fault, Alarm 1 and Alarm 2 outputs. The two alarm levels are fully configurable and can be set as rising or falling, latching or non-latching. To differentiate between each input board a simple mechanical link is required.
