Model No. Description Power Requirements (drawn from host) Remote Switch Maximum
S 2 omentary Switch odule 24VDC, 30mA 6 with RPCs (100mA max) or 12 with SCS-4 (200mA max)
Description:
The momentary switch module ( S 2) allows equipment that’s con-
nected to a remote power control (RPC-series) or 4-step sequencer
(SCS-4) to be switched from multiple locations. The S 2 is placed
between the RPC (or SCS-4) and multiple momentary switches. It
converts the normally open momentary contact closures to latching,
maintained closures. This allows multiple switches in a variety of lo-
cations to activate connected equipment. When the S 2 is con-
nected, a momentary closure on any remote switch causes the S 2
to change the state from open to closed or from closed to open, turn-
ing the RPC (or SCS-4) on or off. The S 2 features dual terminal
strips to connect (2) SPST momentary-style switches. Additional
switches can be added in parallel (6 total for use with RPC-series or
12 total for use with the SCS-4). LED indicators display system sta-
tus (on or off). The S 2 does not require an external power source
as it draws power from the host unit (RPC-series or SCS-4).
Features:
• Compact unit (5"L x 3.279"W x 1.687"H)
• Steel chassis with black powder epoxy finish includes mounting
holes and connection diagram.
• ount to a blank rack panel or rack shelf that’s pre-punched for
electronic devices (Lowell odel No’s. USE-210 or USE-310, order
separately)
• ade in the USA
A & E Specifications:
The device for converting normally open momentary contact closures
to latching maintained closures shall be Lowell momentary switch mod-
ule odel No. S 2. It shall allow for multiple momentary style
switches to be used to activate equipment that is connected to Lowell
RPC-series remote power controls or Lowell SCS-4 sequence con-
troller. The S 2 device shall include 1 terminal strip for connection
to remote power control odel No.______(RPC-series) or sequence
controller odel No. SCS4. It shall also include 2 terminal strips to
connect up to 4 momentary switches odel No.______(RPSB-series)
when connected to a remote control (RPC-series) host; or up to 12
momentary switches odel No._______(RPSB-series) when con-
nected to sequence controller odel No. SCS-4 as a host.
