-ID/OD
Long-distance Communications
Supported by SRT2 Models
(Long-distance/High-speed
Communications Selection)
SRT1 models support high-speed communications
only.
SRT2 models support long-distance communica-
tions and high-speed communications.
Ultra-compact at 80 x 48 x 50 (W x H x D) mm for
4-point and 8-point terminals and 105 x 48 x 50 (W x
H x D) mm for 16-point terminals.
Two independent power supplies can be used
because the I/O terminals are insulated from the
internal circuits.
DIN track mounting and screw mounting are both
supported.
