Wiring the Digital Inputs
EDS-508 has two sets of digital input, DI 1 and DI 2. Each DI consists of two
contacts of the 6-pin terminal block connector on EDS’s top panel, which are
used for other device’s digital inputs. Top and front views of the terminal block
connectors are shown here.
STEP 1: Insert the negative
(ground)/positive DI wires into the /I1
terminals.
STEP 2: To keep the DI wires from
pulling loose, use a small flat-blade
screwdriver to tighten the wire-clamp
screws on the front of the terminal block
connector.
STEP 3: Insert the plastic terminal block
connector prongs into the terminal block
receptor, which is located on EDS-508’s
top panel.
