TIM foils or otherwise known as graphite sheet have been introduced in use in ACS800 mod

ules using EconoPACK+ IGBT as part of normal continuous improvements in the ACS800

product family. Benefits of using TIM foils in comparison to thermal grease are easier installa

tion and more durable heat transferring properties for longer periods of time. Durability par

ticularly improved in a cyclic application.

Where and how to use

TIM foils are used to transfer the heat generated in the IGBT’s to the heatsink. Full instruc

tions on how to install TIM foils is described in document delivered with TIM IGBT spare part

kits. It’s possible to use a mix of IGBT’s with thermal grease and TIM foils. In parallel con

nected R8i modules it’s also possible to use a mix of modules using TIM foils and thermal

grease.

The DO801 is a 16 channel 24 V digital output module for the S800

I/O. The output voltage range is 10 to 30 volt and the maximum

continuous output current is 0.5 A. The outputs are protected

against short circuits, over voltage and over temperature. The

outputs are in one isolated group. Each output channel consists of a

short circuit and over temperature protected high side driver, EMC

protection components, inductive load suppression, output state

indication LED and optical isolation barrier.

Features and benefits

• 16 channels for 24 V d.c. current sourcing outputs

• 1 isolated groups of 16 channels

• Output status indicators

• OSP sets outputs to predetermined state upon communication error

• Short-circuit protection to ground and 30 V

• Over-voltage and overtemperature protection

• Process and power connection via detachable connectors

The DI803 is an 8 channel 230 V a.c./d.c.digital input module for the

S800 I/O. This module has 8 digital inputs. The a.c. input voltage

range is 164 - 264 volt and the input current is 7.6 mA at 230 V a.c.

The d.c. input range is 175 - 275 V and the input current is 1.6 mA at

220 V. The inputs are individualy isolated. Every input channel

consists of current limiting components, EMC protection

components, input state indication LED and optical isolation barrier.
