PRODUCT OVERVIEW

monitoring applications. The board simply mounts onto the rear of a DMS- 30LCD-1-5, allowing both the

application board and the meter to be powered solely from the 4-to-20mA loop input. Align pin 1 of the

board with pin 1 of the DMS-30LCD-1-5 and simply solder the two assemblies together.

potentiometers. Decimal point selections and range changes are all made on an eight-position DIP switch

featuring gold-plated contacts — there are no cumber-

some jumpers or solder gaps to contend with! Connec-

tions to the loop are made via a reliable, screw-type

terminal block. The only assembly tool required is a

screwdriver!

modates hundreds of different display reading combi-

nations. This essentially eliminates the need to order

"specials" in applications in which several differentrange

meters are required. OEM customers should consider using DATEL's DMS-30LCD-4/20S which already

has the DMS-EB-LP soldered to a rugged DMS-30LCD-1-5 digital voltmeter.
