Product Information & Installation Guide
AIR PEAR SERIES - Model 60/EC
CONNECTIONS
M/TIO DESCRIPTION
General
M/TIO modules provide a compact input/output solution for Modbus
RTU master controllers.
The unit has incredibly
fl
e
xible input / output confi
guration that
allows many applications to becontrolled by a single device.
A combination with any Modbus wall unit greatly simplifi
es
installation on the wall-unit side, as
the IO module can be located close to the terminal unit being
controlled, with only communication wiring into the wall unit. The
mains powered versions eliminate the need for additional power
supplies or transformers further reducing cost and installation labor.
M/TIO also hosts a battery backed-up real-time-clock..
Relay Outputs
5 relay outputs are provided. Each relay can be used independently,
and a speci
fi
c set of three can be confi
gured for 3-speed fan control.
Universal Inputs
8 inputs are provided, confi
gurable as below:
Triac Outputs
2 triac outputs are provided with
fl
e
xible confi
guration options,
allowing control of on/off thermoelectric (PWM) or
fl
oating
actuators or relays. The triacs can be independently
confi
gured to control different loads. However, due to internal
connections, all loads must be supplied from the same AC voltage.
Floating (three-position) confi
guration requires use of both
triacs.
Modulating Outputs
Four 0-10VDC analog outputs are provided for controlling
modulating valve or damper actuators. Two of these can be
confi
gured to function as digital inputs.
Expansion Port
Up to two RK4 modules can be connected to the device with a
ribbon cable, providing a total of 8 additional relay outputs
Real Time Clock
4 time-schedules can each be independently associated with a relay
output through confi
guration parameters. Each schedule allows 28
sets of start/stop times per day of the week.
