Digital I/O on
power supply
board
7 digital inputs:
To DIN 19240: Logic “0" equals -3...+5 V, active with logic ”1"
(12...+30 V, max. 25 Hz, max. 32 V, input current
approx. 1.5 mA)
Selectable function per input: Control input (time
synchronisation, set up lock, text display, group selection,
display switch off), impulse counter, on/off event, operation time
counter, combination event + operation time counter
Auxiliary voltage for digital input control when using potential
free contacts, approx. 24 V DC max. 150 mA short circuit
protected unstabilised
Outputs (not SELV circuits):
4 relays closing contacts, 230 V / 3 A for limit infringement
transmission can be set as opening contacts
1 open collector output (max. 100 mA / 25 V)
Digital I/O board
Either 1 or 2 digital I/O boards can be additionally plugged in.
Each of these subsitutes one universal analogue board.
One digital I/O board ontains 15 digital inputs and 6 relay
outputs. For technical data see section “Digital I/O on power
supply board”
Mathematics
package
(four additional, calculated channels; can be cascaded)
mathematical combination of analogue channels, basic
mathematics functions, (+, -, *, /), constants, integration
(quantity calculation of analogue channels) and expanded
mathematics functions: log, ln, exp, abs, sqrt, quad, sin, cos,
tan, asin, acos, atan
Formula schematic:(g (y1) * a) ? (y2 * b) + c;
g = mathematics function
y1/y2 = analogue or mathematics channels
a/b = factors
c = constant
Serial interface
