Module Type F:

Module Type T:

Module Type S:

times less than ten seconds will drastically shorten

relay

life

and in no case should the cycle time be set to

zero (60

millisecond

time

base). Normally open

contacts are provided for both

cooling

use.

NOTE:

Do not use

this

output module

with

mechanical

contactors

because they generate an excessive

EMI

field

which

can

lnterfere

with

other controllers. Instead

we recommend "T" output modules for this applicatlon.

This

4-20

output module can deliver full output to

loads having an input Impedance of 500 OHMS or less.

The cycle

time

setting

must be ZERO for smooth

current output.

A push-on

utilized

as a return for ground

currents of the

milliamp

source. It is connected

Internally to the mating lug on the heatsink. To avoid

ground loops, drive floating (ungrounded) loads or use

isolated thermocouples.

This solid state relay is capable of 1 AMP at

120/240Vac.

zero voltage switched and optically

isolated from the

signal.

With

it,

resistive loads

up to 120 watts at 120Vac and 240 watts at 240Vac

may be controlled

directly.

Using

direct

control there

is no lower

limit

on the cycle time

(down to

milliseconds).

Larger loads may be controlled

utilizing

an external

contactor. In this case, It is

advisable

to use cycle

settings of ten seconds or greater to

minimize

contactor wear. External suppresslon of the contactor

becomes a problem.

Similar

Cycling

without sacrificing relay life.
