Description

This low-cost accessory board provides an easy way of powering all DMS- 30PC-X-RL (red low-power models only), as well as all DMS-30LCD and DMS- 40LCD (non-backlit, +5V-powered models only) panel meters from 100-264Vac (50/60Hz). The on-board AC/DC converter provides an isolated +5Vdc to power the meter's electronics, while providing 1500Vac isolation between the AC supply and the input signal being measured. Line power and input signals connect to two rugged, screw-style terminal blocks (TB1 & TB2) permanently mounted on the DMS-EB-AC/DC. This type of terminal block provides reliable mechanical connections and eliminates the need for any extra wiring harness connectors.

The DMS-EB-AC/DC board includes provisions for installing several usersupplied components that are required when the meter must be scaled to display non-standard input ranges. The DMS-EB-AC/DC has provisions for such common applications as attenuation of high input voltages, gain (span) and offset (zero) adjustments, and direct decimal point placement. The DMS-EB-AC/DC is compatible with all four input versions of the DMS-30 Series meters (±200mV, ±2V, ±20V and ±200V). Solder gaps, conveniently placed on the board, are easily bridged or cut to configure the board to meet each application's specific requirements.
