Product Overview
The IT-R4 is a multi-purpose switch or logic level activated Relay Module. Four user configured relays are
activated and controlled via five input ports that are designed to accept either a switch contact closure or logic
level input. A four position configuration dip switch sets the operating behavior of the relays. Each relay can be
set for different operating modes; “On, “Off”, pulsed for a ¼ of a second or toggled which changes the relay to
the opposite state. For a detailed description of operation and settings see the Switch Input Actuation Table.

Caution:
The IT-R4 and IT-R4S relay interface modules are not intended to directly switch AC line voltages.
Connection to lighting and shade and screen systems should be done at the low voltage control interface
provided by the manufacturer.
If you must interface to AC line voltages, add a relay module designed for this purpose such as the FSR 12 Volt
AC-2 or 12 volt AC-2A.

Setup
The four relays can be configured as indicated in the relay configuration portion of this table along with their
corresponding relay operation. The label is located on the bottom of the unit. The operation of the relays is
accomplished by combining one of the five inputs of either A, B, C, D or E with a selected setting on a fourposition configuration dipswitch located on the main PCB. Switches S1 through S3 are used for accomplishing
this, while the fourth position is used to control the logic state at which the relays will operate. S4 closed allows
active low inputs to turn on the relay while S4 open allows active high inputs to turn on the relay.

Mode Switch Label

Single Relay Interlock Mode (SPDT) Mode Switch Setting 000
This mode provides the ability to control each of the four SPDT relays through switch inputs A through D.
When one relay is activated or turned on, the other relays are turned off. For example if the user turns on Relay
#1 using switch input “A”, then Relays 2, 3 and 4 are turned off. Switch input E turns off all Relays.
Multiple Relay Activation – Alternate Action Mode Switch Setting 001
This mode toggles each individual Relay on or off. The first switch closure turns the relay on and the second
switch closure turns the relay off. Any combination of switches may be activated at the same time. Switch input
E, when activated, overrides all other switch inputs and turns off all relays.
Multiple Relay Activation – Momentary ON Mode Switch Setting 010
This mode turns on the corresponding relay for the duration of the switch closure. Switch E turns on all relays
for the duration of the closure. Any number of relays can be operated at the same time.
Dual Relay Mode (DPDT) - Push On/Push Off Mode Switch Setting 011
This mode provides the ability to pair up the Relays for use in a Dual Relay application. Each pair R1/R2 and
R3/R4 effectively become DPDT relays when configured in this mode. Switch A turns on relays 1 & 2; Switch
B turns off relays 1 & 2. Switch C turns on relays 3 & 4, and switch D turns off relays 3 & 4. Switch E turns
off all relays.
Dual Relay Modes (DPDT) - Alternate Action Mode Switch Setting 100
This mode provides the ability to toggle each pair of Relays. Switch “A”, toggles relay pair R1/R2 and Switch
C toggles relay pair R3/R4. Switch D unconditionally turns on both pairs of relays and switch E
unconditionally turns off both pairs.
Dual Relay Modes (DPDT) Alternate Pulsed 0.25 sec Mode Switch Setting 101
This mode provides the ability to pulse each relay for a given application that may require the use of a trigger
pulse for turning on some type equipment.
• Switch A the first press sends a ¼ second pulse to relay 1; the second press sends a ¼ second pulse to
relay 2.
8
• Switch B when pressed sends a ¼ second pulse to relay 1 on the leading edge; when released it sends a
¼ second pulse to relay 2 on the trailing edge.
• Switch C the first press sends a ¼ second pulse to relay 3; the second press sends a ¼ second pulse to
relay 4.
• Switch D when pressed sends a ¼ second pulse to relay 3 on the leading edge; when released sends a ¼
second pulse to relay 4 on the trailing edge.
• Switch E has no function.
Quad Relay Mode Mode Switch Setting 101
This mode provides the ability to turn on or off all four Relays at once.
Switch A turns on all relays, Switch B turns off all relays, and Switch C toggles all relays. Switch inputs D & E
have no functions.
Special Function Mode Mode Switch Setting 111
• Switch A turns relays 1 & 2 on and sends ¼ second pulse to relay 3.
• Switch B turns relays 1 & 2 off, and sends ¼ second pulse to relay 4.
• Switch C first press turns on relays 1 & 2 and pulses relay 3 for ¼ second. The second press turns off 1
& 2, and pulses relay 4 for ¼ second.
• Switch D the leading edge performs Switch A function, trailing edge performs Switch B function.
Mode Dipswitch 4
Mode Switch 4 determines the control activation state of the 4 relays.
• S4 set to “1”: Inputs A thru E are active Low. The leading edge is the High to Low transition of the
switch input. The trailing edge is the Low to High transition of the switch input.
• S4 set to “0”: Inputs A thru E are active High. The leading edge is the Low to High transition of the
switch input. The trailing edge is the High to Low transition of the switch input.
