Product Information
The Isolation Amplifier 6KA9905 RED is a complete mount and function-compatible redesign of the no longer available model from the original equipment manufacturer Siemens.
The device is assembled in a hermetically sealed plastic housing for panel surface mounting with the assembly flange dimensions 85 x 80 mm, in accordance with the mounting hole clearance of 65 x 68 mm (M4).
The terminal assignment corresponds to the original module.
The isolation amplifier provides amplification in two ranges, which can be selected by divergent clamping.
The bridges between KL. 8 and KL. 9 range 60 m V//10V and KL. 6 and KL. 7 range 150 m V//10V, which are required for the original module, are not required in the redesign.
The galvanic isolation with max. 1000 V is situated between the input and the output of the device.
The output is connected to the ground of the supply voltage and supplies +/- 10 V at a maximum load of 5 mA.
The supply voltage amounts to nominal + 18 …36 V ; however, the device can also be wired with + / - 24 V.
The terminal - 24 V is not internally connected.
The frequency range amounts to 800Hz -3 dB or rather 600Hz -3dB.
