The DSCL21 DIN mount package accepts EN50022 (35 x 7.5) and EN50035 (G32)
type rails; Dataforth SCMXRAIL1-xx or SCMXRAIL2-xx. Multiple DSCL21 modules
may be mounted next to each other without effecting input or output signals.
Screw terminals with wire protection clamps sized for 0.2 to 4mm
2 solid or 0.2 to
2.5mm 2 stranded wires. The DSCL21 may be mounted in any position. The DSCL21
requires no maintenance.
