Functions & Features
• Converts alternating current from a current transformer
into a standard process signal
• Minimum ripple
• Rerouted input signal does not pass through the base
socket in order to protect it from melting caused by rush
current of a motor

MODEL: W2CA–[1][2][3]-[4][5]
Same range availability as Output 1
ORDERING INFORMATION
• Code number: W2CA-[1][2][3]-[4][5]
Specify a code from below for each [1] through [5].
(e.g. W2CA-5AA-M2/CE/Q)
[4] POWER INPUT
AC Power
M2: 100 – 240 V AC (Operational voltage range 85 – 264 V,
47 – 66 Hz)
• Special output range (For codes Z & 0)
• Specify the specification for option code /Q
(e.g. /C01/S01)
(90 – 264 V for UL)
DC Power
R: 24 V DC
Note: If one of the outputs should be a current range,
specify it for the Output 1 to allow a greater load.
(Operational voltage range 24 V ±10 %, ripple 10 %p-p max.)
R2: 11 – 27 V DC
(Operational voltage range 11 – 27 V, ripple 10 %p-p max.)
(Select ‘/N’ for ‘Standards & Approvals’ code.)
P: 110 V DC
[1] INPUT (sine wave)
Current
(Operational voltage range 85 – 150 V, ripple 10 %p-p max.)
(110 V ±10 % for UL)
