RB4C Relay J-BOX
The RB4C provides four FORM-C,
SPDT (one normally open and one
normally closed), 24-250 volt (AC or
DC), 3A mechanical relays to control
external devices from a digital weight
indicator equipped with output control.
The output control can be 5-15VDC,
1mA source or 20mA current sink. The
source (SRC) or sink (SINK) type is
selected with the Relay Control
Source Type Jumpers, J1, J2, J3, and
J4 (see Figure No. 14), one for each
relay.
