ISA data acquisition card PA-1508

digitalcontrol

The PA-1508 16 digital input/output ISA card has 8 digital inputs, 24 V, and 8 digital outputs, 24 V. All the inputs are opto-isolated. It is used for industrial I/O control, for automatic test benches, as an interface to electromagnetic relays, for status monitoring (on/off) of motors, lamps, etc. or alarm activation in a harsh industrial environment and has a number of safety devices to do this. A CD-ROM containing drivers for Windows and programming examples is included. Description Features 8 digital inputs, 24 V, isolated 2 connection lines per input Parallel acquisition of digital 24 V signals Each input channel has its own ground line 8 digital outputs, 24 V, isolated Each output channel can be triggered independently from the others The output channels are current-limited and suitable for loads with high inductive currents 2 diagnostic outputs generate LOW level at overtemperature Watchdog: can be activated through software, readable After power-on the outputs are reset to “0” Addressing through DIP switches Safety features Optical isolation 1000 V Voltage supervision Creeping distance IEC 61010-1 (VDE411-1) Safety for the inputs: voltage reversal protection, LC filters Safety for the outputs: Overtemperature protection: Shut-down logic at approx. 125-140 °C, short-circuit current at 1.5 A, Shut-down logic, when the external supply voltage drops below 5 V. Safety features for the ext. supply voltage: overload protection: self-resetting fuse (electronic fuse), overvoltage protection through varistors and transorb diodes, screened through LC filters EMC tested according to 89/336/EEC (CE certification)
