Page 5: Product Description
The TIP670 has 8 (4) digital outputs with galvanic isolation via optocouplers. The outputs are isolated against each other in groups of two. All outputs resist short-circuits and are protected against thermal overload. -

Page 11: Functional Description
5.1 Digital Inputs 5.1.1 Optical Isolation The TIP670 has 8 (TIP670-10) or 4 (TIP670-20) digital inputs. The standard signal level for these inputs is 24V DC. The switching level of the inputs is between 8 and 13 volts. All input channels are isolated by AC optocoupler and are also isolated against each other. -
Page 12: Output Watchdog
Any software access to the Z8536 will retrigger Timer 3 in the Z8536. If the programmed time expires without a software access all outputs go into the ’off’ state (the maximum programmable time is approx. 30ms). However they will return to their original state, when the TIP670 is accessed again by the software. -
Page 13: Programming
6.1 Required Software Initialization The input lines of the TIP670 are connected to port B of the CIO Z8536. This port has to be configured as input and because of the inverting function of the optocouplers the input polarity has to be set to inverting. -
Page 14: Initialization Of The Watchdog Function
6.2 Initialization of the Watchdog Function On the TIP670 port C and counter timer 3 of the Z8536 are wired in way, that a watchdog function can be programmed into the TIP670. This watchdog is retriggered with every access to the TIP670. If there is no access within a previously programmed time frame, the watchdog will automatically disable the output lines. - Page 15 This selects the Counter/Timer 3 Command and Status Register (C3CSR) for the next operation • Write 0x06 to CIOCSR Writing 0x06 into C3CSR triggers and runs counter timer 3 • Write 0x00 to PORTC Writing 0x00 to PORTC will enable the watchdog function TIP670 User Manual Issue 1.3 Page 15 of 19...

Page 16: Installation
Each input has two connections at the IP I/O connector, Input x + and Input x -. However the TIP670 has AC optocoupler at the input side. Therefore the polarity of the input signal may be either way. -
Page 17: Output Wiring
Each output can be individually configured as a high side or a low side switch by corresponding wiring. Figure 7-2 : Output Wiring as High Side Switch Figure 7-3 : Output Wiring as Low Side Switch TIP670 User Manual Issue 1.3 Page 17 of 19... -
