It is recommended to protect the solid state relay against

overheating. Therefore the chart also states the maximum

switching temperature (70, 80 or 90 °C) for the optional

temperature limit switch.

Applications

RSC -AAM60/RSO....

Energy saving for motors in idle mode

The output module RSO ..110

is recommended for motors

up to 22 kW @ 400 V. The

RSO ..110 is designed for use

in applications with high surge

current conditions. Care must

be taken to ensure proper heat-

sinking when the relays are to

be used at high nominal cur-

rents. Adequate electrical con-

nection between relay termi-

nals and cable must be ensured.

Example 1:

Power dissipation -

RSO 40110:

load

= 40 Arms = 111 W

See previous page.

Example 2:

Motor: 3 kW, 4 HP

3 x 400 VAC, 4-pole

: 50°C

Starting time: ≤ 5 s

For this application RSC-AAM60

must be used. The output

module RSO4025 is selected

according to the Selection Guide.

The smallest heatsink

required is 1 K/W, and the

power dissipation is 25 W.

This gives:

Control module:

RSC-AAM60

Output module: RSO 4025

Heatsink:1K/W

Connection to the mains

Since no motor protective

circuitry is included in the

RSC/RSO, the motor must

be protected in the usual

way, i.e. either by a thermal

relay, a PTC-resistor or a

Klixon bimetal temperature

switch near the motor windings.

If short circuit protection is re-

quired, fuses F1 to F3 should

be ultrafast and selected ac-

cording to the load integral

t) of the RSO output module

and the motor load.

When motors are running idle,

it not necessary to maintain a

full magnetic field, as is the

case when the motor has to

produce full torque. By lower-

ing the motor voltage, power

losses inside the motor are

also reduced.

Transient voltage protection

With an unfiltered main supply,

voltage transient may occur.

Since these transients could

have a high energy content, it

is advisable to use varistors

to protect the output module.

The varistors are already

mounted in the RSO output

module and they are selected

according to the rated opera-

tional voltage.

When the motor is idle, d1 will

switch the control current from

> 20 mA to I

, which is

adjusted to a value at which

the motor is still running at full

speed, but at a lower voltage.

Please remark that this type of

phase-angle controlled voltage

reduction, demands additional

filtering to fulfill EMC regulations.

Applications (cont.)

RSC -AAM60/RSO.....

In order to achieve a 4 to 20

mA signal from a 12 or 24

VDC source, a resistor and a

potentiometer should be con-

ected in series with the volt-

age source and the RSC con-

troller.

We define the I

max.

to be e.g.

24 mA, which means that the

series resistors must be:

(12 V) = U/I - Rint =

12 V/24 mA - 250 Ω = 250 Ω

(24 V) = U/I - Rint =

24 V/24 mA - 250 Ω = 750 Ω

If the minimum current is

efined to be e.g. 2.4 mA

and the 250 Ω Rint input

resistance of the RSC is

also calculated in:

(12 V) = U/I - R

- Rint =

12/2.4 - 250 - 250 = 4500 Ω

(24 V) = U/I - R

- Rint =

4/2.4 - 750 - 250 = 9000 Ω
