MAXIMUM VOLTAGE/CURRENT. Maximum allowable voltage
per crosspoint relay for the relay matrix is 250 V dc or 250 V ac
RMS (350 V ac peak). Maximum current per relay is 1 A dc or 1
A ac RMS (non-inductive). Maximum power input is 40 W (dc)
or 40 VA (ac) per relay. Exceeding any limit may damage the
relay matrix module.
STATIC-SENSITIVE DEVICE. Use anti-static procedures when
removing, configuring, and installing a module. The relay
matrix is susceptible to static discharges. Do not install a
matrix module without its metal shield attached.
The relay matrix consists of a component card and a terminal block. User
inputs to the matrix are to the HIGH (H) and LOW (L) terminal connectors
on the terminal block. Figure 2-1 shows the terminal block features and
Figure 2-2 shows how to connect user (field) wiring to the terminal block.
