1.4.2.2 S-type
S-type boards provide a single set of screws for each I/O point and allow a single I/O pack to condition and digitize the I/O.
They are half the size of T-type boards and are standard base mounted but can also be DIN-rail mounted. These boards can be
used for simplex, dual, or dedicated triple redundant sensors by using one, two, or three modules.
S-type boards have Euro-style, box type terminal blocks. Some boards are available as either removable or fixed terminal
block versions. S-type board terminal blocks accept one 2.05 mm (0.08 in) (#12 AWG) wire or two 1.63 mm (0.06 in) (#14
AWG) wires, each with 300 V insulation per point. Screw spacing is 5.08 mm (0.2 in) minimum and center-to-center.
Box-type Terminal Blocks
These terminal blocks have the following features:
• Green in color with number labels.
• Terminal rating is 300 V, 10 A
• UL and CSA recognized
• Recommended screw tightening torque is 5 lb-in (0.5 - 0.6 Nm)
