A-8
Introduction
Spider8
The passive transducers are connected via commercially
available 15-pin sub-D connectors to the carrier-frequency
channels in the basic device or to an SR55/SR30
carrier-frequency expansion module.
Active transmitters are connected to an SR01 DC expansion
module via a connector with screw terminals which is provided.
D The first two channels in the basic device may alternatively be
used as frequency or pulse counters (only with Spider8 (TF)). All
the inputs can also process 10 V signals directly instead of
transducers.
D A basic device can be expanded to a total of 8 channels using 3
types of module (channel numbers 4 to 7):
- the carrier-frequency module SR55
1)
provides similar options
to the basic channels (but no frequency/pulse counter inputs),
- the carrier-frequency module SR30
2)
enables you to connect
S/G transducers in quarter, half and full bridge connection
(600Hz carrier frequency technology),
- the DC module SR01 extends the Spider8 options for electrical
quantities:
temperature (with thermocouples J, K, T, S or
Pt100/Pt1000),
voltage up to 10 V
=
current up to 200 mA
=
and
resistance up to 4000Ω.
The inputs of the SR01 are electrically isolated.
1)
for Spider8 and Spider8-01/55
2)
only for Spider8-30 and Spider8-01/30
