IQ23x
I/O Channels
IQ Controller Inputs Outputs
IQ111 1 to 8 Universal channels, V, I, T, D 1 to 6 Universal channels, V, I
IQ111+ 1 to 8 Universal channels, V, I, T, D 1 to 8 Analogue V channels
IQ231 1 to 8 Universal channels, V, I, T, D 1 to 8 Analogue V channels
IQ131 1 to 16 Universal channels, V, I, D 1 to 12 Universal channels, V, I
IQ131+ 1 to 20 Channels 1 to 4: Universal, V, I, T
1 to 12 Analogue V channels
Channels 5 to 16: Universal, V, I, T, D
Channels 17 to 20 D only
IQ233 1 to 20 Universal channels, V, I, T, D 1 to 12 Analogue V channels
Generally the IQ23x can accommodate the I/O channel requirements of the controller it replaces. However, the IQ111, 131 had
outputs which could be linked for either current or voltage whereas the IQ23x has voltage only outputs.
If required, current outputs can be provided by adding 2VID, two channel voltage to current interface modules. If an SRMI
has been connected, it can be replaced by an SRMV or 2SRM (dual channel).
Although the IQ131+ can be replaced by the IQ233, the IQ131+ has a special arrangement of input channel types which affects the
fast sequencing of digital inputs (see Firmware section below).
Link Headers:
Link Header Used on Used for Replaced by on IQ23x
LK/A IQ111, 131 Regulated 5V supply at 20 mA LKE/5V
LK/B Regulated 15 V supply at 20 mA LKE/15V
LK/C Regulated 10 mA supply LKE/10mA
LK/D Adds thermistor input capability Link for thermistor T (not required on IQ131 as could be
linked for thermistor inputs)
LK/E Regulated 15 V through 4k7 ohms not supported
LK/F Desensitises digital inputs not required on IQ23x
LK/0 Externally powered current sensor Link for externally powered current sensor Ix
LK/5V IQ111+, 131+ Regulated 5V supply at 20 mA LKE/5V
LK/15V Regulated 15 V supply at 20 mA LKE/15V
LK/10mA Regulated 10 mA supply LKE/10mA
As can be seen from the above table, most of the applications requiring link headers are either achieved by the three new link
headers, or by appropriate input channel linking. The LK/E has no replacement but was rarely used.
Integral nodes
A node controller board may be fitted inside the IQ23x. The IQ23x may be ordered with a board pre-fitted, or it may be post-fitted
using the KIT/NODE/IQ23x. The node may be one of the current range of boards (CNC2, PNC2, INC2, TMNH, TMNE, LINC), or it
may be one of the older nodes (CNC, PNC, INC, MNC, ANC, AND, XNC, XN28, ENC).
Note that the IQ131 did not have a CNC built in to its firmware so that if the IQ131 was to be networked, it required a CNC to be
fitted which was connected directly to the IQ131 via RS232. Alternatively, a stand-alone IQ131 could have a modem connected via
an ANC or MNC, either of which was also connected directly to the IQ131 via RS232. If an IQ131 is replaced by an IQ23x its CNC is
redundant, and if an integral modem node (e.g. ANC, MNC) were fitted, it would now be connected to the controller via the network,
not by RS232 as previously. The IQ111, 111+, and 131+ all had a CNC built in to the firmware so this note does not apply to them.
A CNC was sometimes used for local supervisor or NDP network connection; these can now be connected via the local supervisor
port. The local supervisor port also supplies 24 Vdc to the NDP.
