HSE PLUGSYS

TAM-A Type 705/1 and TAM-D Type 705/2

9.2 Technical data TAM

Construction

PLUGSYS module

Differential input with an input impedance of 10

Ohm through a 6-pin Binder or Amphenol-

Tuchel socket with screw lock. For direct operation of resistive transducers with half-bridge
or full-bridge circuit.

Input

Supply

+5 Volt 350 mA from PLUGSYS system bus

CAL reference

In position CAL, simulate a reference value adjustable by multi-turn trimmer, additionally
zero reference in position OFF

Binder Type 09-0321-00-06 / Amphenol Type T3400501

Input plug

Bridge
supply

5 Volt / 50 mA max.

In the range 10x to 10 000x, selected by internal jumper as x10, x20, x50, x100, x200,
x500, x1000, x2000, x5000 and x10000. The basic gain setting can be varied with the
GAIN control within the range 20-100%.

Gain

1. Autozero by pushbutton
2. Manual zero through multi-turn coarse and fine trimmers

Zeroing

Analogue LED bargraph, 19 LEDs (+12/null/-6) for visual indication of the measurement
signal

Indication TAM-A

3½-digit LED display ±10 Volt / ±100%, or variable to suit the actual measurement

Indication TAM-D

Low-pass with 3 settings 30 - 100 - 300 Hz selected by switch

Output filter

Internally to PLUGSYS system bus: pulsatile output and additional mean value output (0.1
or 0.3 Hz)

Outputs

BNC socket on front panel: pulsatile output or mean value output (0.1 or 0.3 Hz) as se-
lected internally through jumper

19" PLUGSYS module, width 8E (40.5 mm), height 3U (128.7 mm), depth Eurocard (220
mm)

Dimensions

DIN 41612, 96 pin VG
